Renewal of contract maybe not a good idea

I have been a loyal customer of Vodacom for more than 15 years. I went on Saturday to have my contract renewed at Vodacom, Victoria Centre, Heidelberg. The lady who did the renewal of my contract had us sign everything, we left, collected the phones, and thereafter I starting waiting. Phoned her on Monday to ask what the problem was with my second sim, keep on getting SMS's, five different ones, saying my "new quote" has been received, each one with a different reference number. Apparently only the Shop can help me? And all the lady can say to me is it is a system error. Does not give me any confidence to remain a client at Vodacom, this is terrible customer service!
